[GAMEPLAY] Galio - Using E just before being stunned by Viktor's W will ignore the knockdown effect

If Galio is casting E just before the last stack of Viktor's W is applied, he will be stunned but he will be able to dash out of his W (Viktor's W behaves similar to Veigar's E, when the stun goes off, all movement abilities will be interrupted: "knockdown effect")

1. Place Viktor W on Galio
2. Just before being stunned on Galio, press E Galio will be stunned but will dash out of Viktor's W

I've tried this bug with my friend 4 times and all 4 times Galio dashed out of Viktor's W.
